If you have a previous version, use the examples included with your software. If you see any errors or have comments, please let us know. Switching a 125VAC light bulb with a general purpose Relay Relay 5VDC by BARRAGAN Relays enable you to control one circuit from another circuit with no electronic connection between the two circuits for example to control a device (switching it ON or OFF) from the Wiring harware. A Relay is an electric switch capable of switching AC devices by applying a small current at it, making possible to control high AC voltages from the Wiring hardware. Int relayPin = 8; void setup() { pinMode(relayPin, OUTPUT); } void loop() { digitalWrite(relayPin, HIGH); delay(1000); digitalWrite(relayPin, LOW); delay(1000); }

If you have a previous version, use the examples included with your software. If you see any errors or have comments, please let us know. 4N35 General purpose optocoupler by BARRAGAN Optocouplers enable you to control one circuit from another circuit with no electronic connection between the two circuitsfor example to control a toy or device (switching it ON or OFF) from the Wiring hardware without tempering with the toy circuit.

Just interrupt the line you want to control and attach both ends to the S1 and S2 signals.
Playground - TLC5940. The TLC5940 is a 16 channel PWM unit with 12 bit duty cycle control (0 - 4095), 6 bit current limit control (0 - 63), and a daisy chainable serial interface.

It is handy for expanding the number of PWM outputs available. The datasheet is available at Some details about issues discovered using the chip and Eagle footprint for TLC5941: tlc594x and Arduino Download the Arduino Library The source/downloads for the library are on Google Code: Install. Part Search.

It is suited for building robots, data loggers, and devices for human-computer interaction. Its functionality is inspired by the MIT Cricket and many other programmable devices such as the the Lego Mindstorms, the IRX board, and Basic Stamps. What’s new in this version? USB Connection. A Brief History The initial designers of the GoGo Board are Arnan (Roger) Sipitakiat and Paulo Blikstein. Goals The main goal of the GoGo Board project is to create an open-source platform that is designed to be low-cost and allow for local assembly by those who are interested. Commercializing GoGo Boards Although the hardware design and software are release under the GPL license, building and selling boards does not violate the license as long as all the design source are provided and made obvious.

Problem with most of the camera is, that it's using almost 20 pins when connecting to CPU. There are eight pins for Y-bus (gray-scale image) next eight for U-bus (color channel) and three pins for clock, frame-sync and h-sync. After that, camera is usually required to be connected over I2C, for configuration settings (brightness, contrast, rotation etc.) Luckily there is the company called COMedia Ltd., producing still image cameras connected over serial interface. Cameras can be purchased from Electronics 123.
